Data transfer will be faster in packet switching providing the setup time in circuit switching is greater than the time required to send a packet. If not, that is setup time in circuit switching takes less time, then circuit switching is quicker.
In circuit switching there is also some required overhead; the overhead in packet switching is usually a small percentage of the total traffic; and in any case, the benefits of packet switching far outweigh any disadvantage of some minor overhead.

Packet Switching =)
Packet Switching - Computer Communications (Digital)Circuit Switching was used for old fashioned telephony. At present, many companies use VOIP (Packet Switching) for voice communications.
telephone system uses packet switching because packet switching is reiable. In a packet switching when a packet(some part of total information) is lost then the packet can be retransmitted. But in case of circuit switching if any part of data is lost anytime then total data will be retransmitted. Again circuit swithing is more speedy with compare to packet switching.In order to increase the bit rate (more speed) circuit switch is prefered in Internet.
1. circuit switching 2. packet switching
There are three basic hardware building blocks of a host. These include the Transmission Control Protocol (TCP), client technology, as well as Packet Switching.
packet switching
Circuit switching and Packet switching are used in Telephony. Circuit switching is used in voice communication and packet switching is used in transmission of data packets to provide internet connection.
1.circuit switching statically reserves the required bandwidth in advance whereas packet switching acquires & releases it as it is needed. 2.With circuit switching any unsed bandwidth on a allocated circuit is just waisted.with packet switching it may be utilised by other packets . 3.Circuit switching needs to set up an end to end path before any data can be sent. 4.When packet switching is used it is straight forward for router to provide speed and code conversion. 5.In packet switching packet may be delivered in the wrong order. 6Packet carriers usually base theier charge on both the no. of bytes(or packets carried and connect time. 7.with circuit switching, the charge is based on the distance and time only, not the traffic.
